Now I just have to decide if I should pay the extra $$ to get it through Sony for my 505 so it's correctly formatted, or get it through Fictionwise for a bit less, but then have to convert. Hmm. Probably worth the $1.50 per book to just get it nice and clean.

Sony's versions have huge margins that waste screen space. I find it preferable to try to get a version that I can reformat according to my own taste. Plus, if you can get it without DRM (or if you can remove the DRM, like with MS Lit format) then you can keep the book for future ebook devices. The problem with Sony's format is that you can't do anything with it.
